Ethyl 2-(indol-3-yl)-2-oxoacetate is a hydroxy derivative of the amino acid tyrosine. It inhibits the enzyme tyrosine hydroxylase, which catalyzes the conversion of tyrosine to L-DOPA. This in turn affects dopamine synthesis and has an inhibitory effect on rat brain. Ethyl 2-(indol-3-yl)-2-oxoacetate also inhibits methylmagnesium borohydride in vitro, which is a reagent that breaks down esters, amides, and nitriles. Tyrosine hydroxylase is inhibited by the presence of two hydroxy groups on the ethyl side chain and one hydroxy group on the indole ring. It can be used as a structural analogue for other drugs that are used to treat Parkinson's disease or depression.

3-Phenylbut-2-enoic acid is a prochiral, carbonyl compound that can be used in the synthesis of chiral pharmaceuticals. Mechanistic studies have shown that 3-phenylbut-2-enoic acid is a catalytic hydrogenation reagent that converts prochiral substrates to their corresponding chiral products. When combined with binap and butenoic acid, 3-phenylbut-2-enoic acid can catalyze the asymmetric synthesis of butenoate. The reaction yields high enantiomeric excesses and good yields.

6-Chloro-9-(propan-2-yl)-9H-purine is an intermediate in the synthesis of nucleoside analogues. It is obtained by the catalyzed reaction of acetonitrile and purines, which undergoes regioisomerization to form a mixture of 6-chloro-9-(propyl)- and 6-chloro-9-(butyl)purine. This intermediate can be used for the alkynylation of amino acids or peptides with alkynes. The selective formation of one regioisomer can be achieved by using a chiral catalyst or by reacting with an optically active reagent such as (+)-camphor sulfonic acid.

1,2,3,4,5-Pentachlorobenzene is a chlorinated hydrocarbon that is used in the production of pesticides and herbicides. It is an ingredient in the manufacturing of pentachlorophenol and pentachloronitrobenzene. 1,2,3,4,5-Pentachlorobenzene has been used as a chemical intermediate or solvent for the production of other chemicals. The emissions from this chemical can be harmful to humans and animals because it has been shown to affect enzyme activities at sublethal doses. It also affects rat liver microsomes and causes DNA damage that can lead to cancer.

2,2-Dibromopropane is a synthetic chemical that has been used as a precursor in the production of nylon. It is an activator that can be used to form covalent bonds with reactive groups on other molecules. The activation energy for the reaction with piperazine is between 104 and 106 kJ/mol. 2,2-Dibromopropane undergoes acylation reactions under certain conditions, forming reaction products such as 2,2-dibromoethyl acetate and 2,2-dibromoethanol. The molecular weight of 2,2-dibromopropane is 192.19 g/mol and its structural formula is CHBrCHBrCHBrCHBrC≡C≡C≡C≡C≡C≡CC(O)OH.

1-Monotetranoin is a fatty ester that is involved in the process of lipolysis, which is the breakdown of fat cells. Lipolysis occurs when an enzyme called lipase hydrolyzes triglycerides into glycerol and three fatty acids. 1-Monotetranoin has been shown to be a potent stimulator of growth factor production and cell proliferation in vivo models. It has also been shown to be effective at inhibiting angiogenic processes in vitro, including the release of growth factors from fat cells. The neutral pH optimum for 1-monotetranoin is between 7 and 8, which may be due to its hydrophobic nature.
